Is my apache a proxy to ad servers?

Hi guys,

today I noticed this on my access.log file repeated many times.

220.160.81.187 - - [29/Oct/2004:23:55:49 -0400] "GET
http://oz.valueclick.com/cycle?host=...es=468x60&t=js
HTTP/1.0" 200 322 "http://www.nets888.com/" "Mozilla/4.0 (compatible; MSIE
5.5; Windows NT 4.0)"

my web site is not "oz.valueclick.com"

What does this mean?

Does this mean that my apache is getting the file and then serving it the
requester?

I don't have a file by the name "http://oz.value...." anywhere
under /var/www/html

How could they get such a file from me?

I don't mean to sound quite this harsh, but if you don't know if
Apache is proxying then turn Apache off until you find out. As a
matter of fact, turn off all daemons that you don't understand.

HINT:
locate httpd.conf
less /PATH/TO/httpd.conf
/proxy
